SLIDING-DOOR LOCK.

SPECIFICATION forming part of Letters Patent No. 293,593, dated February 12,- 1884.

' Application filed November 13, 1883. (Modem To aZZ whom it may concern:

Be it known that I, SAMUEL S. PETERSON, of Wyandotte, in' the county of Wyandotte, State of Kansas, have invented a new and-useful Improvement in Fastenings for Oar-Doors, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, making a part of this specification, in which Figure 1 shows the front elevation of a freight-car door with my improved fastenings Fig. 4 are details to describe the exact manner in which I have carried it out.

In the drawings, A represents the side of a freight-car provided with the door B, hung on ways and caused .to slide in the usual wellknown manner. In the side of the car, and

flush therewith, I secure the metal block 0.

This block is provided with the vertical dovetailed slot or groove D, the opening of the slot flaring near its top to receive the dovetailed tenon on the block E, whereby the block E is readily and easily attached to and detached from the block 0. When the block E is in position for use, as shown in Fig. 1, its edge fits snugly up to the edge of the door B, whereby the door is held steadily in position when closed. The outer face or edge of the block E is nar- Fig. 3 is a see rowed, so as to receive the hasp F, as shown in 40 Fig 1. Nearthe edge of the block is a perforation, G, through which passes the key H, for locking the hasp F on the block E, and the lower end of the key H is perforated to receive the usual seal-applied to freight-car fastenings. It is evident that this seal might be applied to the block Eat, the perforation G, and thus secure the hasp in place; but the friction of the hasp, caused by the shaking of the cars, would have a tendency to damage the seal, if not to destroy it altogether but when the seal is attached to the lower'end of the key II it is evident that the seal is free from all'such danger. I secure the key H and block E by chains, in order to avoid the possibility of their being lost or mislaid.

The operation of my improved fastening is as follows: The door B having been closed, the block E is slipped into position in the slot D, I and the hasp E.is placed in position over the block. The key H is then dropped into the perforation G and secured by a seal in any of the well-known ways.

Havingthus described my invention, what I claim as new, and desire to secure by Letters "Patent, is-

In a ear-door fastening, the grooved metal blo ck'O,provided with the dovetailed groove D, and themetal block E, provided with a dovetailed tenonfitting into the dovetailed groove D, and perforated to receive a slotted key or seal, H, in combination with the hasp F, pivotally secured to the car-door, all substantially as shown, and for the purposes described.
